The diameter expansion connecting wire is light in weight, simple to machine and reliable in structure, and can tolerate gale and rainstorm weather.
Description
Technical field
The present invention relates to a kind of hole enlargement connecting line, relate in particular to a kind of outdoor extra-high voltage experiment hole enlargement connecting line.
Background technology
On extra-high voltage GIS (gas insulated combined electrical equipment) test platform, need the frequent change mode of connection to obtaining the different tests data.Because electric pressure is higher, pass through electric current, the corona noise etc. of connecting line are had relatively high expectations.When adopting engineering with hard wire, it is well positioned to meet through-current capability and than the low noise level requirement, for example adopt the 4 supporting conductor spacers of division JLHN58K-1600 wire of engineering reality, but its weight is very big, general reconfiguration line needs crane and several personnel to match just to complete, if need frequent reconfiguration line need expend a large amount of manpower and materials.another measure is to select the masking foil Telescopic corrugated pipe, its weight is little, can different-diameter customized satisfy the requirement of corona noise, for example the patent No. is the Chinese utility model patent of a CN99225495.7 Telescopic corrugated pipe, this bellows is upper oblique line Duan Bobi by the cross section, in declivity line segment ripple wall and connection, the garden arc crest of declivity line segment ripple wall and upper, the triangle trough that declivity line segment ripple wall self forms consists of, but it is because lifting surface area is larger, high-altitude in the ultra high voltage grade, easily occur damaged under the weather such as strong wind heavy rain, reliability is lower.
Summary of the invention
For the deficiencies in the prior art, the outdoor extra-high voltage experiment hole enlargement connecting line that the invention provides that a kind of replacement cost is low, noise level is low, can use for a long time, reliability is higher.
concrete scheme of the present invention is: a kind of outdoor extra-high voltage experiment hole enlargement connecting line, comprise conductor spacer, stressed wire, conductive braided fabric line and stopping means, described conductor spacer is circular, surface at described conductor spacer, around alternate the first through hole and the second through hole of being provided with in the center of circle of conductor spacer, the aperture of described the first through hole is greater than the aperture of described the second through hole, described stressed wire passes the second through hole, and with the inwall contact of described the second through hole, described conductive braided fabric line passes the first through hole, described stopping means is fixed on stressed wire, and be positioned at the both sides of conductor spacer.
Further, described stressed wire is the stainless steel silk thread.
Further, described conductive braided fabric line is copper litzendraht wire.
Further, described conductor spacer is the aluminum annulus.
Further, the iron sheet of described stopping means for clamping.
Further, described conductor spacer internal diameter is 40cm, and external diameter is 44cm, and thickness is 3mm.
Further, described conductor spacer surface is respectively equipped with 4 the first through holes and the second through hole.
Further, the aperture of described the first through hole is 8mm, and the aperture of described the second through hole is 5mm.
Further, the diameter of described stressed wire is 3mm.
Adopt technique scheme, technique effect of the present invention has:
The present invention is that a kind of weight is little, and processing is simple, reliable in structure, the connecting wire device that possesses tolerance strong wind heavy rain weather, its hole enlargement design can effectively suppress to produce under high voltage the phenomenon of corona, can give full play at the trial safety, advantage flexibly, reduced experimentation cost, higher economy has been arranged.
The present invention adopts the aluminum conductor spacer to reduce connecting line weight and proof strength, and the conductive line surfaces field intensity is reduced, and reduces the corona impact; Connecting line is selected two kinds of different materials cross arrangements, gives full play to the satisfactory electrical conductivity of the higher tensile strength of steel wire rope and copper material; The relative position fixing means of conductor spacer and wire is simple and easy to safeguard; Integrated connection line apparatus weight is little, can singlely complete connection work.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
As depicted in figs. 1 and 2, a kind of outdoor extra-high voltage experiment hole enlargement connecting line, comprise conductor spacer 1, stressed wire 2, conductive braided fabric line 3 and stopping means 4, due to the test relevant to test platform, in general normal current is no more than 10A, therefore adopt engineering also unnecessary with the hard wire of large cross section, cross-sectional area 20mm
2Copper cash can satisfy through-flow demand.When pressing grade to reach 1100kV, use single 20mm
2Its surface electric field intensity of copper conductor can surpass discharge inception voltage, can cause larger corona noise on the one hand, can bring the harmful effects such as radio interference to other equipment on the other hand, therefore consider to adopt the bundle conductor form to reduce the conductive line surfaces field intensity.the required conductor spacer 1 of bundle conductor is circular, be preferably the aluminum annulus, internal radius is 40cm, external diameter is 44cm, thickness is 3mm, surface at conductor spacer 1, around alternate the first through hole 5 and the second through hole 6 of being provided with in the center of circle of conductor spacer 1, preferred interval is provided with 4 the first through holes 5 and 4 the second through holes 6 uniformly, the aperture of the first through hole 5 is greater than the aperture of the second through hole 6, the aperture of the first through hole 5 is 8mm, the aperture of the second through hole 6 is 5mm, because the tensile strength of copper cash is lower, choose the stressed wire 2 of stainless steel of diameter 3mm in the present embodiment as main stress point, it passes, and on conductor spacer, diameter is the second through hole 6 of 5mm, and with the inwall contact of the second through hole 6, what the relative position between stressed wire 2 and conductor spacer 1 was fixed utilization is the higher stopping means of intensity 4, because conductor spacer weight is little, stopping means 4 is directly chosen and is clamped iron sheet fixed intervals rod 1 position and get final product.The copper conductive braided fabric line 3 that plays electric action passes the first through hole 5 of conductor spacer 1.Because copper conductive braided fabric line 3 does not play stressed effect, and for avoid its damage as far as possible, what it passed is that diameter is the hole of 8mm, leaves larger leeway.
As shown in Figure 3, due to stressed wire 2 and conductive braided fabric line 3 softer, take interval 2.5 meter amperes to put a conductor spacer in the present embodiment, can guarantee to be difficult between wire being crossed as sub-thread.The connecting line length of the present embodiment is not more than 50 meters.
Should be noted that at last: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, although with reference to above-described embodiment, the present invention is had been described in detail, those of ordinary skill in the field are to be understood that: still can modify or be equal to replacement the specific embodiment of the present invention, and do not break away from any modification of spirit and scope of the invention or be equal to replacement, it all should be encompassed in the middle of claim scope of the present invention.
